Hello everybody!

I recently bought a sound system for home:

2x Electro-voice ELX215 Dual 15-inch two-way full-range
2x Electro-voice ELX118P Powered 18-inch subwoofer
1x Behringer iNUKE NU3000DSP @220v
1x Denon DJ DN-X600 Professional 2-Channel Digital Mixer

And it sounds great but i do not feel that punchy bass in my old Sony mini hi-fi system...

I was just wondering if i had bought Sony shake music system if it would be more powerful ?( the original package comes with 2 speakers, but it saids that we can party chain stereos together so...)

Thanks for your support !

 

[manoli337]

Or you might have an advice for me to make my system sound better?...

Could be a wrong setup. Did you check the phase between subs and main speakers? The subs don't seem to have an adjustable phase angle and you're running the main speakers full range I presume. One easy check: if the bass gets better with the subs switched off, you're definitely in phase trouble.

 

[manoli337]

alright im gonna check today! but look at this:

 

[markbakk]

That still doesn't offer you even reverse polarity, let alone adjustable phase shift as is found on a lot of subwoofers.

i dont very understand :/

what is adjustable phase shift ?

and how can i correct the problem ?

sorry im not very familiar with theses terms ....

There's a lot to learn... With the speakers you have a 60hz crossover will be the best compromise.

Since it doesn't sound like you have measurement capabilities I suggest leaving the sub out for now. Take a picture of your setup and room. Will be easier to make suggestions.

Hi , how to set the crossover on he Inuke 3000 DSP?
i have the dsp software on pc so it could be easier...


Here's a picture of my room:


That is a schema that i draw of the pluggings:







Hope it helps

This is a home system? You really have to turn it up very loud to get good sound out out of something like that. I would cross it over at about 100HZ and 125HZ for the sub.

 

[manoli337]

Yeah its for my home theather ahah,

How can i put a crossover? :/

And with thé crossover, is it going to sound better?

Thx

The output from your mixer goes into the crossover. Given that you have a 2 way crossover the low output goes into an amp that you power the subwoofer and the mid/high output goes into another amp that you will power the mid/high cabinets.

You adjust the level at the crossover. If your amps has gain setting turn it all the way up. Do all your level adjustment at the crossover front panel. I would set the frequency between 100hz-125hz.

PA speakers will give you the maximum SPL, but it will not give you the sound quality of a good home speakers.

Since your subs are powered the low output from the crossover will go directly into the sub.

You've all missed it.
You're running the subs out of the booth monitor, which is an independent output from the main mix.



For each XLR output on the desk:

XLR goes out of the desk, and into the subwoofer. Do this bit first.
Then another bit of XLR goes from the subwoofer to the iNuke, which powers the tops.

Make sure your top speakers are wired up to the amplifier properly (store-bought SpeakOn cables will be fine) and you're set to go. Adjust the volume on each subwoofer equally - if you turn one up, turn the other up the same.


Since you've got the iNuke DSP, read up on how to do an active crossover on it. You only need a high-pass, set for 100Hz. Butterworth 24 should do the trick.

Yes, I've missed it. I didn't see the photos I'd assumed he was running external crossover from the main mix.

Oh okay , for the pluggings, i drew it to be shure i've understood well.

But for the crossover i have Gain ,Low pass and High pass. It just depends on the sound configuration : Stereo, Dual , Bi-amp 1, Bi-amp 2 and Bridge. So witch one do i choose?

 

[chris661]

You've understood correctly.


Stereo (this sets it so that both channels have the same processing):
You want to set gain = 0dB
High pass = But 24
High pass frequency = 100Hz

 

[manoli337]

It wont cause any problems if my subs are powered and that i plug it into an amp?

Here's the screen of my amp to make shure that i set it right before testing it

Your sub takes the XLR input, and splits it in two - one is passed on to another subwoofer, or a different amplifier using the XLR output. The other is used for its own amplifier.

You're perfectly safe, but feel free to upload photographs if you'll feel more comfortable.


Edit - those crossover settings are correct.

just a little question before, : Why is there two lugs in the back of my elx 215 if im only using one ?

thanks
